Connecting at Miami on American: is 45 minutes enough?

Numbers from Aug 2025 – Jul 2026 flight records · generated 29 September 2026

Miami is the US's biggest gateway to Latin America and the Caribbean, and American — its dominant carrier here — runs most of its own flights from two side-by-side concourses, D and E. GateCast grades US flight connections A–F from a year of real delay data.

ABCDFHow the pairs in each band are graded

"Missed" means the first flight was cancelled, or arrived too late to leave about 31 minutes to get off, reach the next gate and board before the doors close. That time is our estimate for American connections here: flight records don't say which passengers made their connection. Days when the second flight was cancelled aren't counted. Pairs scheduled less than 35 minutes apart are left out, because we can't tell which of those the airline would sell as a connection.

Tight · 4h 47m at MIA

Two separate tickets

AAAmerican Airlines 2963MIA to MCO · leaves 15:50
B
Good · 2h 48m at MIA
These are two separate tickets, not one booking. If the first flight runs late and you miss the second, you're not owed a seat on it. Passengers typically paid $162* one way from MIA to MCO. Graded B. The connection itself is rarely missed: the grade comes from the arrival. On the days both flights ran, American 2963 reached MCO typically 4 min late, 13% of days more than an hour late.
